Coles staff deal with 500x the promos
99% of these do not require manual involvement at store level, these are managed by the trade pricing team in the head office, setting up bombs and similar (you would know what's a bomb against a SKU if you have any knowledge on discount and promo).
So these have nothing to do with something like 'how many gift cards you can sell'
Also, cash registers now run Windows (whereas cash registers I used ran on 256k RAM + something stupid like 16k ROM), so things like purchase limit can also be set by the pricing team in SAP. This is why cash registers in Coles won't let you scan more than 5 gift cards.
So, again, there maybe stuffs which need to be managed on store level, but these are really minimal.
not the staff member, and a distinct lack of leadership.
It is not the responsibility of the leadership to make a check out staff read the newsletter, or the promo cheat sheet. It is up to the staff to do it, and do what's right by the customer and by the company.
If someone tells me that they "don't have enough time" to read the comms before starting their shift and be aware of anything they should be aware of, then their heart and mind is not at the job. To argue with a customer without checking their notes or notices while challenged, is just bad practise in the customer or hospitality sector.
Imagine if a customer were to ask, whether the Teens gift card could be used at Boost Juice, and you say yes, because it used to, but it actually no longer works at Boost, and the customer buys the Teens gift card based on your Yes answer. You would have caused your employer to breach ACL, but more importantly, you would have caused the customer to lose money by buying a gift card which they can't use, and made their day, from a happy day looking forward to a sugary Boost Juice, to a shatty day with no Boost Juice and losing however much money they wasted on the gift card.
I would never do something which Happy Dude experienced. That's just a poor form in so many ways.
